The reason that the tele-pods from 'The Fly' as a mode of transport would never be commercially viable is that you would have to travel to work naked each morning. I don't think people would be comfortable arriving each day at the office with their business all hanging out. 'Morning Johnson!', 'Morning sir!', 'Cold out today I see!'.
The only time it wouldn't matter i suppose is for Porn Stars and Glamour models. It's pretty much their job to be naked so it would actually save them a bit of hassle getting ready in the morning, just to take it all off again. Some how I don't think Seth Brundle created the tele-pods so that porn stars could get to work hassle free.
